UNITED STATES PATENT O FICE.

JOHN 0. BROWN AND G. H. SLIMPERT, OF FINGKNEYVILLE, ILLINOIS.

IMPRGVEMENT IN GANG-PLOWS.

To all whom it may concern: I

Be it known that we, JOHN 0. BROWN and G. H. SLlMPERT, both ofPinckneyville, in the county of Perry and State of Illinois, haveiuvented a new and Improved Gang-Plow; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making a part of thisspecification, in which- Figure 1 is an elevation of one side of ourimproved plow. Fig. 2 is an elevation of the opposite side of themachine. Fig. 3 is a top view of the machine with the driversseatremoved. of the machine with the ends of the plowbeams broken away.

Similar letters of reference indicate corre sponding parts in theseveral figures.

Our invention relates to that class of maehines in which twotransporting-wheels are employed in conjunction with plows which arearranged in gangs one behind the other, the wheels being so constructedand applied to the frame of the machine that one of them will runoverthe nnplowed land and the other in the furrow, at the same time keepingthe machine level.

One object of our invention is to prevent the plows from being liftedout of the ground when. the land-wheel moves over rising and fallingland or across corn furrowed land.

Another object of our invention is to facilitate the turning of themachine by making the land-wheel a caster-wheel and locating it in rearof the axle of the furrow-wheelandalongside of the plow which is on thelandside of the machine, as will be hereinafter described.

Another object of our invention is to employ self-locking levers inconjunction with plowbeams whose ends are allowed to rise or fall, saidlevers being so arranged and applied that the driver, while riding uponthe machine, can elevate the plows and lock them in such position ordepress the plows, and, when desired, adjust them toward or from thelandside of the machine at pleasure, as will be hereinafter described.

Another object of our invention is to secure the plows to beams whichare pivoted to the frame of the machine in such mannerthat the Fig. 4 isan elevation of the rear end points of both plows are about the samedistance from the pivotal connections of their respective beams for thepurpose of enabling both plows to run at the same depth in the,

To enable others skilled in the art to under 7 stand our invention, wewill describe its con struction and'operatiou. y

The frame of the machine consists of two longitudinal beams, A A, whichare secured in position parallel to each other by transverse braces,which braces also sustain a platform, A This frame is mounted upon twotransporting-wheels,B and O, and constructed with a view ofapplying thedraft-pole to it in such manner as to avoid side draft upon the team asmuch as possible. This draft-pole Dis secured to the frame by means oftransverse bolts a a ,,which also assist in strengthening the frame.

The drivers seat is mounted upon asta-ndard, E, at the back of which isa frame, Gr, havin g two vertical slots through it, through which thep10w=beams F F pass, as shown in Figs. 3 and 4. These slots are ofsufficient length to allow the plows to be lifted up free from theground, as shown in Fig. 1, or depressed and made to run in the ground,asin Fig. 2, and

the slots are of sufficient width .to admit of all the lateraladjustments of the plow-beams re quired. The plow-beam F, which'is onthefurrow side of the machine, is pivotedzor connected by a bolt to aperforated rocking bar, a, which is pivoted at its ends to thelongitudinal beam A and an intermediateylongitudiual beam, A3, asshown-in Fig. 3, and the plow-beam F, which is on the landside of themachine, is pivoted or otherwise connected to a transverse rocking bar,a, which is pivoted,

some distance in rear of bar a, to the beams A and A The two plow-beamsF F vary in length in proportion tothe distance between thetwo rockingbarsa a, and carry on their rear ends the plows H H, which may be madeof the most approved form.

The standards b b of the plows consist respectively of a verticalportion and a horizontal'portion, which latter is used in securing theplows in the desired position to the beams. These standards are securedby pivots at c c and by set-screws at 0 0 which latter pass throughslots which are made through the standards. By loosening the screws 0 cthe plows can be set at any desired pitch without detaching. them fromtheir standards. The plows are secured to their standards so that oneplow, H, will be in advance of the other, H, and so that they will be atequal (or nearly so) distances from the pivots of their respectivebeams. By this arrangement of the plows and beams the former can beraised out of the ground or made to enter the ground together.

. They will also run at a uniform depth in the ground, whereas if theplow-beams were of difl'erent lengths, or the plows attached to them, ashitherto, the latter would not enter or leave the ground simultaneously.

On the rear side of the frame G are two slotted guides, d'd, through theslots of which the plow-beams pass, as shown in Fig. 4. These plates areboth laterally adjustable, and are secured to frame G by means of screws6 e e e,

which pass through transverse slots through the plates at d, which whenloosened can be moved to the right or left, as occasion requires.

' The forward ends of the plow-beams can be also moved laterally andsecured at any desired point'to their respective bars a a, a number ofholes being made in said bars to admit sot such adjustments.

The upper ends of the laterally-adjustable plates or bars or guides d dhave bearings ff for two levers, J J, which are formed with hooks ontheir short arms, and to the extremities of these hooks rods J J arepivoted, as

shown at t i. The lower ends of the rods J J are pivoted to theplow-beams. vers J J are thrown forward, as shown in Figs.

When the le- 1 and 3, so that their long arms rest upon the foot-standK, the points i i will be moved forward of the pointsff or fulcra of thelevers, and the beamsF F will besustained positively in an elevatedposition,as shown in Figs. 1 and 4. When thelong arms of levers J J aremoved backwardand the points i t pass back of vertiealplaneiintersecting the fulcra of the levers the beams FjF will descendand assume the position shown in Fig. 2. Either one or both plow beamsmay be raised or depressed at pleasure, and this can be done by thedriver 'while sitting upon his seat. levers J J upon the adjustableslotted guides By sustaining the d dit will be seen that the plow-beamscan be adjusted, as above described, without interfering with the properworking of the levers.

this sector g, and when the beam L is in aline with the beam A the frameof the machine will be leveled for running over level surfaces, as showninFigA; but when this beam Lis adjusted as shown in Fig. 2 the machineis ready for plowing. The wheel 0 being applied to a standard, 0, whichis pivoted to the beam L, as shown in the drawings, it will be seen thatit forms a caster-wheel and admits of the machine being turned shortaround with verylittle difficulty. It will also be seen,byreference tothe drawings, Figs. 1, 2, and 3, that the landwheel 0 is located in aposition opposite to the forward plow and some distance in rearofthefurrow-wheel. The latter wheel is arranged in front of the forward plow,and is intended to run in the furrow made in the previous round, whilethe former or land wheel is intended to run on the unplowed ground. Byarranging these wheels B and (l as above described the depth which it isdesired to run the plows can be regulated and the plows prevented fromrising out of the ground in consequence of the wheel 0 passing over cornfurrowed land, or land which is otherwise very uneven.

Having thus described our invention, what we claimas new, and desire tosecure by Letters Patent, is 1 1. While not claiming a caster-wheel forthe purpose of adjusting the plow, we do claim the arrangement of thehinged adjustable beam L with a caster-wheel, G, in the manner and forthe purpose herein described.

2. The use of self-locking levers J J for raising or depressing theplows, applied to the adjustable guides d 61, substantially asdescribed. 3. Connecting the hooked locking-levers J J to the plow-beamsby means of bent swinging rods, substantially as described.

4. The laterally-adjustable slotted plates d 61, applied to the slottedframe G, and adapted to serve as "guides for the plow-beams F F, andalso .as bearings forlevers which are used to raise and depress saidbeams, substantially as described.

5. Pivoting the forward ends of the plowbeams to rocking bars a a, whichare arranged one in advance of the other, and applying the plows to saidbeams at about equal distances from their respective pivotalconnections, substantially as described.
